PRINTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 379,884, dated March20, 1888.

Serial No. 242,462. (No model.)

10 shown in the annexed drawings, making part of this specification, inwhich- Figure 1 is a section on the line 1 1 of Fig. 2, whichis a rearelevation showing the roll of paper and the printing device in positionfor 1 use.

The same letters of reference denote thesame parts.

The roll A is hung so that it can be unwound, to which end the roll iswound upon the roller 20 B, which turns upon the shaft 0, in turn heldin the arms 01 d of the bracket D.

The device for printing the impressions E, Fig. 2, is shown at F. Aroller, f, bearing the form f being printed, is journaled in the The endplates are united by means of the bar f, Fig. 2. One or moreinking-rolls, f, are journaled in the end plates, so as to apply ink tothe form f as the roller f is rotated. The roller fis held 30 to causethe form f to bear upon the web a as the roll is unwound, and therebyproduce an impression E upon the web; The most desirable means thereforis the arm G, to whose bar g the device F is attached, the bar f of 5the device, by means of the projection f and the set-screw 9, beingadapted to be slipped upon the bar g and secured thereto.

The device can be adjusted laterally upon the bar 9 to enable theimpression to be made 0 at the center or toward either side of the weba. The arm G is j ournaled at in the bracket D, to enable the roller fto be moved toward the roll A as it diminishes in diameter, and thesprings act to thus move it. The arm G, or whatever means are used tothus hold the roller f against the web, can, however, be supported fromany other suitable support. as well as from the bracket D. Any suitablemeans, also, can be employed to ink the form f.

To operate the improvement, the end a of the web is drawn out and theroll A thereby unwound. By reason of the form f bearing upon the web theroller f is rotated, and with every rotation of the roller the form fcomes in contact with the web and an impression is produced. It will beseen that the roll A not only supplies the surface to be printed, butalso serves as an impression-cylinder.

The improvement is well adapted to the printing of advertisements uponwrappingpaper, for the same act which unwinds the web produces theimpression, and without letting go of the end of the web a desiredlength of paper can be cut off by means of the knife H.

\Ve claim 1. The combination of the bracket D, the arm G, and spring 9,actuating said arm, with the bar 9, secured to said arm, andtype-printing device F, laterally adjustable on said bar, substantiallyas described.

2. The combination of the shaft 0 and roller B thereon, the bracket D,and arms (1, in which said shaft is journaled, with the spring-actu--STEPHEN G. ADAMS. JOHN B. SEYMOUR, JR.
